Dan Romero clarifies misunderstandings about the MPP protocol and emphasizes its compatibility with multiple chains and payment methods.

Dan Romero clarified common misconceptions about Multi-Party Payment Protocols (MPPs) in an article published on the X platform, emphasizing that MPP's design goals are simplicity, scalability, and cross-chain compatibility, eliminating dependence on a single platform or payment method. These include: 1. No Tempo Limitation: MPP supports any payment method, including cryptocurrencies and fiat currencies, has been extended to the Bitcoin Lightning Network, and has a Solana extension draft. 2. Fees are Not Fixed at 1.5%: MPP itself has no inherent fees; different payment methods may charge different fees, similar to existing payment methods. 3. Openness: MPP Day 1 already supported four payment methods: Tempo (stablecoin), Stripe (multi-payment method), Visa (credit card), and Lightspark (Bitcoin Lightning Network). Any party can quickly scale it, and it has been submitted to the IETF as a Web standard. 4. Not Just Session-Based: MPP supports both on-demand payments and session payments (payment channels). The latter is suitable for multiple small, consecutive payments, reducing API round trips and improving speed. 5. Not just designed for Tempo/Stripe: The MPP structure is simple and easily scalable, does not rely on specific smart wallets, stablecoins, or blockchains, and achieves secure HTTP communication and payment channel separation, enabling rapid integration with Visa and Lightspark.
